Question

A red car is stopped at a traffic light waiting for it to turn
green. Meanwhile, a blue car moving at 15 m/s is approaching the
same stop light. When the blue car is still 20 m away from the
light, it turns green, and both cars accelerate, the red one at 6
m/s2, the blue one at 2 m/s2.
(a) How far apart are the two cars after 1 s?
(b) How far has the red car traveled when the blue car passes
it?
(c) Can the red car eventually overtake the blue car again without
exceeding the speed limit of 30 m/s?
